In the description, identical or similar reference numerals indicate identical or similar components. The following description of the embodiments of the present disclosure with reference to the drawings is intended to explain the general inventive concept of the present disclosure, and should not be understood as a limitation of the present disclosure.
[0027] In addition, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It will be apparent, however, that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and devices are illustrated in block diagram form in order to simplify the drawings.
[0028] According to one general inventive concept of the present disclosure, a combination cable is provided, comprising: a row of cables, the row of cables comprising a plurality of cables spaced apart from each other along a width direction of the combination cable, each cable extending along a length direction of the combination cable; and a first film and a second film respectively provided on opposite sides in a thickness direction of the combination cable, the thickness direction being perpendicular to the width direction and the length direction of the combination cable, the first film and the second film being respectively bonded on each cable, and the first film and the second film between adjacent two cables are not bonded together.

The first film 201 and the second film 202 are respectively arranged on opposite sides of the combined cable in a thickness direction Z perpendicular to the width direction X and the length direction Y of the combined cable, and are respectively bonded to each cable 100, and the first film 201 and the second film 202 between adjacent two cables 100 are not bonded together. Specifically, the row of cables 100 has a first side surface (i.e., as shown, an upper side surface) and a second side surface (i.e., as shown, a lower side surface), wherein the first side surface and the second side surface are respectively located on opposite sides of the combined cable in the thickness direction Z, the first film 201 is bonded to the first side surface of the row of cables 100, and the second film 202 is bonded to the second side surface of the row of cables 100, but the first film 201 and the second film 202 between adjacent two cables 100 are not bonded together, so that the row of cables 100 can be connected and fixed together by the first film 201 and the second film 202 to improve the defect that the internal cables are easy to fall off and loose, thereby improving the structural stability of the combined cable, and since the first film 201 and the second film 202 between adjacent two cables 100 are not bonded together, the flexibility of the combined cable can be improved to avoid the defect that the hardness of the combined cable is too large, difficult to bend, and thus difficult to be welded to the circuit board. Figure 1 As shown, the first film 201 comprises an intermediate portion 201a and bonding portions 201b, 201c located on both sides of the intermediate portion 201a along the width direction X of the combined cable. Similarly, the second film 202 also comprises an intermediate portion 202a and bonding portions 202b, 202c located on both sides of the intermediate portion 202a along the width direction X of the combined cable. Wherein the bonding portion 201b of the first film 201 and the bonding portion 202b of the second film 202 are bonded together on one side of the row of cables along the width direction X of the combined cable, and the bonding portion 201c of the first film 201 and the bonding portion 202c of the second film 202 are bonded together on the other side of the row of cables along the width direction X of the combined cable, so that the connection stability of the first film 201, the second film 202 and the row of cables 100 can be improved. Moreover, the adhesive of the bonding portion is not in contact with the outside air, and is less affected by the environment, so it is not easy to fail. Figure 1
[0030] As shown, the first film 201 comprises an intermediate portion 201a and bonding portions 201b, 201c located on both sides of the intermediate portion 201a along the width direction X of the combined cable. Similarly, the second film 202 also comprises an intermediate portion 202a and bonding portions 202b, 202c located on both sides of the intermediate portion 202a along the width direction X of the combined cable. Wherein the bonding portion 201b of the first film 201 and the bonding portion 202b of the second film 202 are bonded together on one side of the row of cables along the width direction X of the combined cable, and the bonding portion 201c of the first film 201 and the bonding portion 202c of the second film 202 are bonded together on the other side of the row of cables along the width direction X of the combined cable, so that the connection stability of the first film 201, the second film 202 and the row of cables 100 can be improved.
